From a PLC programmers perspective, which Hardy Instrument should I use with my PLC? The HI 3030, HI 4050, HI 2151/30WC, HI 2110WI, the HI 200 DeviceNet module or one of the PLC plug in modules?
I have an older HI 2151/20 and want to upgrade to a current model. Is the HI 2151/30 WS the direct replacment?
What steps are necessary to replace a HI 2151/20WC with a HI 2151/30WC?
